GEORGE WILLIAM IVILKIN SON, OF KENSINGTON, COUNTY OF MIDDLESEX,

ENGLAND.

SOLDERlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 312,941, dated February 24, 1885.

Application filed August 5, 1884. (No model.) Patented in England April 8, 1884, No. 6,073, and in Belgium April 30 1884, No. 64,889.

To aZZ whom it may concern:

Be it known that I, GEORGE WILLIAM WIL- KINsoN, a subject of the Queen of Great Britain, residing at Kensington, in the county of Middlesex, England, have invented a new and Improved Soldering-Iron, (for which I have obtained Letters Patent in England, No. 6,07 3, dated the 8th day of April, 1884, also in Belgium, No. 64,889, dated the 30th day ofApril,

to 1884,) of which the following is a specification.

My invention has for its object a new and improved soldering-iron, by which I am enabled to economize the gas used by obtaining a more perfect combustion, which also prevents soot from accumulating, which is now the case with gas soldering-irons such as those used for the work of stained glass artists, besides avoiding much of the fierce blaze and heat of such soldering-irons.

In order that my invention may be more fully understood, I have appended hereunto a sheet of drawings showing my invention practically carried out.

Figure 1 is a part sectional elevation of one of my soldering-irons for working in the most usual manner upon stained-glass work. Fig.

2 is a part plan of the same. Fig. 3 is a part plan of the soldering-iron adapted to upright Work for more minute manipulation. Fig. 4

is an end view of the junction-block A.

In Figs. 1 and 2, B is the removable copper bit, which is heated and which is actually brought to bear upon the work, this bit be- 3 5 ing screwed on supportD in orderthat it may be conveniently interchangeable for other shaped bits, as is well understood inthe trade.

0 is the deflector or shade, and D is a support for said deflector and copper bit.

0 E is the flexible pipe conveying the gasto the burner F. G is the cock for regulating the supply of the same, and II is the handle by which the soldering-iron is manipulated, and so far there is great similarity between 4 5 this and the irons. heretofore used.

The front pipe, J, and the back pipe, K, are connected together by the junction-piece or equivalent arrangement, A, in whichthe airpassage M is formed. The small reducing or 5o inlet piece, nose, or nozzle Nis also contained therein, and may be either attached to the pipe K or to the junction-block A. The position of this inlet-piece N to the air-passage M is of importance, as is also the size of the inlet-passage a through the said inlet piece, nose, or nozzle, which for the apparatus shown I have found to work well if, say, onefourteenth of an inch in diameter.

The action is as follows: As the gas travels through the inlet-passage a a certain amount of air is carried with it up the pipe J and burned in combination with the gas at the burner-holes s s s, and so perfect is the combustion by this apparatus in the proportions shown that theiron may be worked for hours without any inconvenience and irregular leaping or flashing of the light. Such irons are ready for use, say, one and a half minute after lighting, and the economy of gas is very great indeed.

It will be clearly understood that the positions and shapes of the bit B may be adapted to circumstances. Thus in the modification shown in Fig. 3 the bit B is arranged in vertical position and supported on a boss extending upward from tube J. This tube divides into two branches on each side of this boss, and these branch tubes extending vertically upward on each side of said bit and parallel thereto have series of burners s on their inner sides, through which holes jets of flames are directed upon said bit.

Having therefore now explained my invention, what I claim is In a soldering-iron, the combination of the 8 5 deflector 0, burner F, and bit B,with the front pipe, J, and the back pipe, K, the latter having a nozzle, N, which discharges through a perforation, a, and an air -passage, M, into which the gas from the back pipe is discharged 0 to mingle with the air before entering the front pipe, J, substantially as set forth.

In testimony that I claim the foregoing as my own I EtffiX my name in the presence of two witnessses.
